Abstract
The utility model provides a double glass fiber wrapped polyimide film and mica tape wrapped copper flat wire, which comprises a conductor and an insulating layer, wherein the conductor is a copper flat wire (1); the insulating layer is of a layered structure, and the polyimide film (2), the mica tape (3), the first insulating resin paint layer (4), the double-layer glass fiber (5) and the second insulating resin paint layer (6) are sequentially arranged along the radial direction of the copper flat wire. The utility model uses the polyimide film to improve the voltage breakdown resistance of the wrapping wire; the mica improves the corona resistance of the lapped wire, the glass fiber improves the strength of the lapped wire, and the flexibility is improved.
Description
Technical field
The utility model relates to a kind of wrapped copper strap wire.
Background technology
Enamelled wire is a principal item of winding wire, is made up of conductor and two ones of insulating barriers, and bare wire forms through repeatedly painting, curing behind annealing softening again.But producing is the conformance with standard requirement, satisfy the product of customer requirement again and be not easy, it is subjected to raw material quality, technological parameter, production equipment, factor affecting such as environment, therefore, the mass property of various enamelled wires has nothing in common with each other, but all possesses mechanical performance, chemical property, electrical property, hot property four big performances.
Because motor manufacture level development both at home and abroad is rapid; particularly external high-output power, the try one's best small and exquisite electric machine structure and the environmental protectionization of production process have proposed harsh specification requirement for the lapped wire of motor stator parts: as require lapped wire to have proof voltage, anti-corona, high strength and the good performance of pliability.At present, also there is not to reach fully the lapped wire that as above requires.
Summary of the invention
The purpose of this utility model is to provide a kind of can satisfy proof voltage, anti-corona, high strength and the good lapped wire of pliability simultaneously.
The purpose of this utility model is achieved in that a kind of double glass fiber bag polyimide film and the wrapped copper strap wire of mica tape, comprises conductor and insulating barrier, and described conductor is a copper strap wire; Described insulating barrier is a layer structure, radially is followed successively by polyimide film, mica tape, the first insulating resin enamelled coating, double glazing silk and the second insulating resin enamelled coating along described copper strap wire.
The described first insulating resin enamelled coating is silk-covered wire lacquer 1448-2; The described second insulating resin enamelled coating is silk-covered wire lacquer 1448-2.
Described double glazing silk is the two-layer alkali-free glass wool of rightabout coiling.
The beneficial effects of the utility model are:
1, the utility model uses polyimide film to improve the proof voltage breakdown performance of lapped wire; Use mica to improve the corona resistance of lapped wire, use glass fiber to improve the intensity of lapped wire, increase pliability;
2, the wrapped copper strap wire of the utility model double glass fiber bag polyimide film and mica tape is as high-performance motor, electrical equipment winding wire, has high-tech, new material characteristics cheaply;
3, the utility model is a kind of proof voltage, anti-corona, high strength and the good lapped wire of pliability, and simple in structure, easily manufactured, dependable performance, can be widely used in high-voltage motor, and its withstand voltage is 1.3～1.7 ten thousand Kv.
Description of drawings
Fig. 1 is the structural representation of product of the present invention.
Embodiment
Below in conjunction with accompanying drawing, technical solutions of the utility model are elaborated, but protection range of the present utility model is not limited to described embodiment.
A kind of double glass fiber bag polyimide film and the wrapped copper strap wire of mica tape comprise conductor and insulating barrier, and described conductor is a copper strap wire 1; Described insulating barrier is a layer structure, radially is followed successively by polyimide film 2, mica tape 3, the first insulating resin enamelled coating 4, double glazing silk 5 and the second insulating resin enamelled coating 6 along described copper strap wire; The described first insulating resin enamelled coating 4 is silk-covered wire lacquer 1448-2; The described second insulating resin enamelled coating 6 is silk-covered wire lacquer 1448-2; Described double glazing silk 5 is two-layer alkali-free glass wools of rightabout coiling.The specification of conductor of the present utility model and insulating barrier can be handled by national standard.
Claims (3)
1, a kind of double glass fiber bag polyimide film and the wrapped copper strap wire of mica tape comprise conductor and insulating barrier, it is characterized in that: described conductor is copper strap wire (1); Described insulating barrier is a layer structure, radially is followed successively by polyimide film (2), mica tape (3), the first insulating resin enamelled coating (4), double glazing silk (5) and the second insulating resin enamelled coating (6) along described copper strap wire.
